问题 选择题

Three minutes earlier ____ we could have caught the early train to Philadelphia.

A.or

B.but

C.and

D.so

答案

答案:C

题目分析:考查固定句型:本题中名词短语相当于祈使句的省略句,句型是:名词+and简单句,题干可换成“条件句+陈述句”结构,即If we had set out three minutes earlier,we could have caught the early train to Philadelphia.句意:再早3分钟,我们就能赶上去费城的早班车了。选C。

点评:这个句型和“祈使句+and+陈述句”这个句型很相似。其中的祈使句相当于if引导的条件状语从句,如果陈述句表示否定,用连词or。
